TUBULAR BRUSH Application filed March 25, 1930. Serial No. 438,686.

This invention relates to new and useful improvements in brushes and more particularly to brushes adapted to be used for removing and cleaning the accumulated coating 15 of sulfate and oxide of copper, dirt and other foreign matter from the exposed ends of automobile battery posts.

The object of the invention is to provide a cylindrical or tubular form of brush which is adapted to encircle, cover and enclose a binding post so that the inwardly disposed bristles of the brush will engage all sides of the post and so that by the turning of the brush the bristles will engage and bear upon the cylindrical surface of the posts in a way to clean the same, as is desired preparatory to the operation of disconnecting and connecting terminals, as frequently become necessary.

It is a further feature of the invention to arrange the bristles of the brush tangentially so that they will not be disposed toward the center or axis of the post when applied thereto but will all be deflected to one side tangentially with respect thereto in a way to permit the brush to be more readily applied, especially if the film or' coating of foreign matter upon the post is relatively thick. This arrangement of the bristles of the brush also insures the brush being always turned in one direction, better to smoothly clean the post and prolong the life of the brush. This arrangement of the bristles prevents them from being jammed upward into the brush holder when applied to a post and further permits of the more ready application and smoother operation of the brush.

With these and other objects in view, the invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described,

illustrated in the accompanying drawings,

and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departure from the spirit, or sacrificing any of the advantages of the invention.

Similar characters of reference denote like section of the brush shown in Fig. 1

Fig. 3 is a bottom end view of the brushes shown in both Fig. 2 and Fig. 4; and

Fig. 4 is a longitudinal sectional view of a double ended tubular brush constructed in accordance with my invention.

In the drawings I have shown two forms of the invention, one of which includes a single tubular brush and the other a tubular dual or double ended brush in which instance two sizes of brushes could be provided in a single implement, if desired.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several figures, 6 indicates a tubular metal or composition holder which may obviously be of any desired length and diameter. The brush end 7 of this tube is preferably larger in diameter than the handle end 8, thus forming an annular shoulder 9 substantially midway of the length of the tube where the two diameters intersect.

10 represents a handle which may be formed of wood or composition and whose shank portion 11 is shown seated in the upper smaller end portion 8. The outer peripheral surface of the brush holder is preferably knurled as at 12, better to permit of the turning or rotation of the brush after it has been applied to a binding post.

A ringer washer 13 is positioned in the brush end of the tube against the before men tioned shoulder 9 so as to allow the tubular back or bristle support 14 to be positioned thereaga-inst. A somewhat similar though slightly larger washer 15 is seated against the outer end of the tubular back in which' the bristles are secured, and the lower annular edge portion of this end of the tube is rolled in, as at 16, upon the washer 15 in a way to snugly secure it against said tubular back 14.

This back is preferably formed of leather though can be made of a composite material. The bristles 17 are preferably formed of Wire and may be made of individual U-shaped members, the loop ends of which are secured in the back 14 while the free end portions are disposed tangentially with respect to the center of the holder when the flexible back 14 is rolled into tubular form.

The mouth end of this tubular holder is a little larger than the inner end as is also the brush carried therein, better to allow the latter to be quickly applied and removed from a binding post which is usually tapered.

The double ended brush shown in Fig. 4 is substantially like that shown in Fig. 2 except that the handle member is omitted and that the two end portions of the tube are of like tapered formation, having an annular groove formed in its surface midway of its length to form shoulders 9 against which washers 13 are seated. In this form of brush the groove may be omitted and the inner ends of the brushes seated against each other. The brush structure as well as the outer washer l5 and the turned-in annular edges 16 are substantially like that shown in Fig. 2; the cylindrical pocket 18 in the lower brush shown in Fig. 4 is slightly larger in diameter than that of the brush shown in the upper end, so as to provide two different sizes of brushes in a single holder.

In the use of this last mentioned form of the invention, one end would obviously serve as the handle by which to manipulate the tool while the other end is being applied for cleaning a post.

Having thus described my invention, what l claim and desire to secure by Letters Patent 1s:-

1. A tubular brush of the class described, comprising a cylindrical holder having an annular shoulder formed therein, a tubular form of brush member positioned with the holder, the end of the cylindrical holder being turned in to retain the tubular brush member intermediate the shoulder and said turned-in end portion, the bristles of said brush being all disposed in a like manner tangentially with respect to the axis of the brush holder.

2. A brush of the class described comprising a cylindrical holder, a tubular form of brush member positioned within the holder, the bristles of said brush being straight and all disposed in a like manner tangentially with respect to a cylinder about the axis of the brush holder better to permit the brush to v be turned in but one direction.
